At first glance, tennis betting odds can look a little confusing. However, once you know how to read them, they’re actually quite simple.

## Moneyline

When you are looking at betting odds, the first thing you will see is the moneyline. The moneyline is simply the odds for a given tennis match. The moneyline will either be a positive or negative number. If the moneyline is positive, that means that the player is the underdog and will pay out more money if they win. If the moneyline is negative, that means that the player is the favorite and will pay out less money if they win.

### American Odds

American odds are the default odds at American sportsbooks. However, Vegas casinos will sometimes offer what’s called a “moneyline”. Essentially, a moneyline bet is just a bet on which player will win the tennis match.

The vast majority of moneyline bets in tennis are on the outright winner of the match (i.e. Player A to beat Player B). However, you can also bet on who will win each set separately. betting odds will look something like this:

Player A (-250)

Player B (+200)

In this case, Player A is the favorite and Player B is the underdog. The minus sign (-) indicates that Player A is favored to win and the plus sign (+) indicates that Player B is favored to win.

The number next to the odds (250 and 200 in this example) tells you how much money you would need to bet in order to win $100. In our example, if you wanted to bet on Player A, you would need to risk $250 in order to win $100. On the other hand, if you wanted to bet on Player B, you would only need to risk $100 in order to win $200.

### Decimal Odds

When betting on tennis matches, you will often see odds expressed in decimal form. For example, if the decimal odds are 3.00, then for every $1 you bet, you will win $3 in return.

If the decimal odds are 2.50, then for every $1 you bet, you will win $2.50 in return.

And if the decimal odds are 1.20, then for every $1 you bet, you will win $0.20 in return.

Generally speaking, the lower the decimal odds are, the more likely it is that that particular player will win the match.

### Fractional Odds

Fractional odds are the simplest form of tennis betting odds, and they are popular in the United Kingdom. They are displayed as two numbers separated by a slash, e.g. 5/1 or 3/2, which represent the amount of profit you will make if you bet £1 and win. In order to calculate your winnings using fractional odds, you simply multiply your stake by the numerator (the first number) and then divide it by the denominator (the second number). So, using our earlier example, if you bet £2 on a tennis match at 5/1 odds and your player won, your total winnings would be £10 ((£2 x 5) / 1)).

Decimal odds are displayed as a decimal number, e.g. 2.50 or 1.60, and they represent the amount of money you will receive if you bet £1 and win. In order to calculate your winnings using decimal odds, you simply multiply your stake by the decimal number and then subtract 1 from the result. So, using our earlier example, if you bet £3 on a tennis match at 2.50 odds and your player won, your total winnings would be £7.50 ((£3 x 2.50) – 1)).

## Spread/Runline

### American Odds

American odds are the default odds at American sportsbooks. If a line is -110, then you have to bet $110 to win $100. American odds of -110 imply that the sportsbook thinks the chances of the event happening are about 50%. If the odds are +110, then a $100 bet would win you $110. A +110 bet implies about a 45% chance of the event happening.

### Decimal Odds

Decimal odds are the easiest to understand – simply multiply your stake by the decimal shown and you’ll receive your total winnings (including your original stake).

For example, if the odds were 2.50 and you wagered $100, you would receive $250 in total winnings ($100 x 2.50 = $250), including your original stake.

To work out the implied probability of decimal odds, convert them into fractional odds, and then take the denominator and divide it into 1.

For example, the decimal odds 2.50 can be converted into fractional odds of 5/2. Then, take the denominator (2) and divide it into 1: 1/2 = 0.50 (or 50%). This means that the probability implied by decimal odds of 2.50 is 50%

### Fractional Odds

Fractional odds are the simplest way to bet on tennis matches, and they are popular in Europe and other parts of the world. To calculate your winnings using fractional odds, you simply multiply your bet by the odds. For example, if you bet £10 on a player at 5/1 odds and they win, you will win £50 (5 x £10).

Decimal Odds

Decimal odds are more popular in continental Europe and Australia, and they are very easy to understand. To calculate your winnings using decimal odds, you simply multiply your bet by the decimal odds. For example, if you bet €10 on a player at 2.50 decimal odds and they win, you will win €25 (2.50 x €10).

Implied Probability

Implied probability is a way to convert betting odds into a percentage chance of an event happening. This can be useful when trying to compare different bets. To calculate implied probability, you simply divide 1 by the decimal odds. For example, if a player has 2.50 decimal odds, their implied probability of winning would be 1/(2.50) = 40%.

## Over/Under

When you are looking at tennis betting odds, the over/under is the number of games that are likely to be played in the match. This is different from the moneyline, which is the amount of money that you could win or lose on a bet. The over/under is usually given as a number, such as 21.5. This means that there are 21.5 games that are expected to be played in the match.

### American Odds

American odds are the default odds at American sportsbooks. They are also called moneyline odds. Moneyline means betting on which player will win the match outright, without any regard to spread or handicap.

The winning player will be paid out at odds corresponding to their probability of success. The bigger the long-shot bet, the higher the payout and vice versa. So, betting on the favorite will usually result in a smaller profit than betting on the underdog, everything else being equal.

Positive (+) American odds signify an underdog (‘dog) and negative (-) American odds signify a favorite (‘chalk’).

For example, say Rafael Nadal is playing Juan Martin del Potro in the men’s singles final of a grand slam tournament and Nadal is a -200 favorite (‘chalk’) and del Potro is a +150 underdog. A successful $100 wager on Nadal will return $50 while a successful $100 bet on del Potro will return $250 (plus the initial $100 stake).

### Decimal Odds

In tennis betting, decimal odds are most often used. These are displayed in the following format: 2.00, 3.75, 4.50 etc. How do you read these? It’s actually quite simple.

If the decimal odds are 2.00, this means that for every dollar you bet, you will win $2. So if you bet $10 on a player at 2.00 odds and they win, you will receive $20 back — your original stake plus your winnings.

If the decimal odds are 3.75, this means that for every dollar you bet, you will win $3.75. So if you bet $10 on a player at 3.75 odds and they win, you will receive $37.50 back — your original stake plus your winnings.

As you can see, the higher the decimal odds are, the more money you stand to win for each dollar you bet (assuming your bet is successful).

### Fractional Odds

Fractional odds are the most popular way to bet on tennis in the UK and Ireland. To calculate your winnings using fractional odds, simply multiply the amount you bet by the fraction listed.

For example, if somebody bets £10 on a tennis match at odds of 3/1, they stand to win £30 if their bet is successful – their initial stake of £10 is returned, plus they win £20 from the bookmaker.

If the odds are presented as a decimal, you will need to do a little bit of math to calculate your winnings. Decimal odds are calculated by adding one to the fractional odds – so 3/1 becomes 4.0, or 4-to-1 in decimal form.

To calculate your winnings from decimal odds, simply multiply your stake by the decimal listed. So, if someone bets €10 on a tennis match at 4.0 decimal odds, they will win €40 if their selection is successful – their initial stake of €10 is returned, plus they win €30 from the bookmaker.
